Logging & Observability

Structured logging with correlation IDs and context propagation.

When to Use This Skill

• Need request tracing across distributed services
• Want structured JSON logs for aggregation
• Require performance timing for operations
• Building background workers with metrics

Core Concepts

Effective observability requires:

1. Correlation IDs - Track requests across services
2. Structured logging - JSON format for machine parsing
3. Context propagation - Carry metadata through async calls
4. Performance timing - Measure operation durations
